  • Publication number: 20090117183
    Abstract: The method produces a lactose-free oral contraceptive composition containing a combination of a gestagen and an estrogen together with one or more pharmaceutically acceptable auxiliary agents and/or excipients. The contraceptive composition is a tablet, powder, or capsule that contains the gestagen and estrogen, filler material such as microcrystalline cellulose and a binder such as hydroxypropylcellulose, but no lactose. Preferably the gestagen is dienogest, chlormadinone acetate, or levonorgestrel and the estrogen is ethinylestradiol, 17?-estradiol, or estradiol valerate. A method is provided for improving the prophylaxis of lactose intolerance in women taking oral contraceptives. The oral contraceptive preparations for a standard 28-day cycle or for long-term use contain at least 21 daily dose units of the gestagen and the estrogen in a low-dosage but without lactose and at most 7 daily dose units containing no active ingredient or a placebo.

  • Patent number: 6977083
    Abstract: The method of making a bioadhesive tablet for controlling testosterone blood level, especially in elderly men suffering from partial androgen deficiency, includes spray-drying an alcoholic solution or suspension of testosterone and at least one testosterone ester, preferably in a ratio of 1:10 to 1:1.5, separately or together, with an organic polymer and optionally one or more auxiliary ingredient to form an active ingredient premix. Then various other auxiliary ingredients are mixed, as needed, with the active ingredient premix to form the bioadhesive tablet with an active ingredient layer and an adhesive layer. The active ingredient layer contains an effective amount of the active ingredient premix. The adhesive layer includes auxiliary ingredients including the bioadhesive polymer. The bioadhesive tablet may be buccally administered to provide a predetermined timed release profile of testosterone, advantageously varying according to a circadian rhythm.
